Genetic mapping information

Copy number variation (CNV) analysis identifies a deletion on chromosome 2L with breakpoints occurring in approximately 3kb windows whose midpoints are coordinates 2L:19423344 and 2L:19962150 .

    NOT in combination with other aberrations

    The Df(2L)Sd37 chromosome does not act as a dominant suppressor of telomeric silencing (assayed using the effect of the chromosome on the eye colour phenotype of flies carrying "P{wvar}KR3-2", a stable "brown-red" variant of the P{3'WP-2,wvar}2Lt insertion).
